I live in a house of boys. My mini men do not have large appetites (yet), but we do run through a lot of bread.
As such, my first tip is to buy ahead and freeze your loaves.
Buy extra loaves of bread and freeze them.
My second tip is to keep bread loaves in the refrigerator.
Keep a loaf of bread in the fridge.
If you purchase the loaves and freeze them, they are often past the expiration date once you need to use them and will require refrigeration. Even if they are not, keeping them in the fridge extends their life and delays molding.
Bonus tip: I also keep all the bread ends and use them for French Toast.
Keep the bread loaf ends, or heels, for use in French Toast.
If you’re a better homemaker baker than I; heels may also be used for breadcrumbs, croutons, bread pudding, trails out of the woods, and stuffings.
